//! Controller actions implementation
//!
//! This file contains:
//! - Controller assignment and activation actions following OpenSCENARIO specification  
//! - Override actions for manual control (throttle, brake, steering, gear)
//! - Controller configuration and parameter setting per OpenSCENARIO XSD schema
//! - Gear control types (manual/automatic) and supporting enumerations
